A more thorough explanation:

A conspicuous place is a location where it is easy to see notices or signs. This means that the place is visible and noticeable to people who are passing by.

For example, a bulletin board in a busy hallway is a conspicuous place because many people walk by it every day. Another example is a sign on a building that faces a busy street.

These examples illustrate the definition of a conspicuous place because they are locations that are easily seen by a large number of people. This makes them ideal for posting important information or notices that need to be seen by many people.
